To all whom it may comem:

Be it known that I, PETER SARTORY, a subject of the King of Great Britain and Ireland, residing at Bayswater, London, England, have invented certain new and useful Improvements in Exothermic Heaters, of which the following is a specification.

This inventionl relates to heaters used in water is to react toproduce the heat required, can be placed in the heater during manufacture, and the water brought into contact with the substance when the heater is disposed in a heating tube.

According to the invention an exothermically operatingl heater for use in steaming a tress or hair coiledA upon a curler, comprises a stratum of a chemical material which will react exothermically with a liquid reagent, formed to extend lengthwise of the tress to I besteamed, and a juxtaposed fibrous stra- '.tum which is capable of acting as a distribuft'o'rof valliojuid reagent to the chemical maf terial which reacts exothermically with said vmaterial.,v j .a

The' accompanying `drawings illustrate preferredconstructions according to this inventidue-'I Figs. .l and 2 are plan and cross sectional viewson` one form of chemical heating pad accordance with the present invention.

Serial N0. 757,934.

Fig. 7 is a side View partly in section of one form of tubular chemical hea-ting pad in accordance with the present invention.

Referring to Figs. l and 2, 1 indicates a heating pad or jacket comprising a porous envelope of cheese cloth, paper or the like divided into pockets by rows 2 of stitching, and provided with a flap or extension 3; the pockets being filled with powdered or granular calcium oxide, indicated at 4.

in Fig. 3 the pad illustrated at Figs. l and 2 is shown applied to a tress of hair arranged upon a curler 6, the chemical material being supported by the porous fabric of which the envelope is made, the ap 3 being first wrapped round the curled tress to protect it from contact with the material 4, and also forming a lining to the pad. This lining gives additional protection to the trees treated' without stiiiening the envelope.

As shown, water is applied to the heating pad by enveloping the same in cotton wool or like fibrous material 7, such as can be saturated with water, and which may be in the form of pads; the whole being enclosed-ina steaming tube 8 of compressed fibre or other material. Such an arrangement provides a heater having an inner annular layer ofchemical material vand an outer layer of brous material.

The steaming tube 8 is divided longitudinally,asindicated at9 (Fig. 6),each section having a slotted end plate 10 adapted to em brace the root end of the tress, the sections of the steaming tube bein detachably held together by a clip 1l pre 'erably secured to one section. 1

en the tube is assembled .it compresses thel saturated pads 7, so expressing the water into the heating vmaterial 4 of the pad or jacket l' whereby an exothermic reaction is initiated, which develops sumcient heat for steaming the enclosed trees without rrislr ot injury to the hair.

If desired a split rubber disc 12 ofy known form may be secured over the ligament or projecting end of the tress to prevent steam from injuring the seal while the other end of the tube 8 may be llft o n, as shown.

lReferring to ig. 7 the eating ad l is arranged as a tubular member, an is carv riedon a skeleton member in the form of a light perforated tube,1-3 of c lindrical section, which may be of meta and which, with the fabric material of the envelope,

adl

g i atomic acts as a sup rt for the chemical material; the pad 1 being envelo ed in an absorbent layer 7 secured by ties a.

Such a heater can be packed up Aiii boxes as refills for steaming tubes constructed as herein described, or as described in copending 'application Serial No. 730,122, and my copending application 757 ,935 for Improvements in steaming tubes.

By the present invention a process of curling and waving human hair on the head is obtainable wherein the heat required for steaming is generated locally, thereby eliminating any external source of heat energy, e. g.,electric power units.

l. claim :ff-

l. An exotherinically operating tubular heater for use in a steaming tube when steaming a tress of hair arranged upon a curler, comprising in combination a skeleton member of cylindrical section, a porous envelope carried by said skeleton member, a chemical substance in the envelope and a layer of fibrous material on the outside of said envelope, the chemical material bein such as to react exothermically with a liqui and the iibrous material being ca able of acting as a distributor of the liqui reagent to said chemical material.

2. An exothermically operating tubular heater for use in curling and waving human hair upon a curler, comprising the combination with a sup ort including a skeleton member of cylin rical section,and aporous fabric covering said member, of

a layer of chemical material surrounding said fabric, and a layerof brous material surrounding the chemical layer, such chem= ical material being such as to react exothermically with a liquid and lthe iibrous maten rial being capable o acting as a distributor of the liquid tothe chemical layer.

3. An exothermically operating tubular heater for use in steaming a tress of hair comprising in combination an inner layer of chemical material contained Within a supporting porous envelope, a Hap to said envelope forming a lining to said heater, and an outer layer of fibrous material, the chemical material being such as to react exothermically with a liquid and the fibrous material being capable of acting as a distributor of the liquid reagent to said chemical material.

4. An exothermically operating tubular.

heater for use in a steaming tube when steaming a tress of hair arranged upon a. curler, comprising in combination a skeleton member of cylindrical section, a porous envelope carried on said skeleton member, a. chemical substance in the envelope, a marginal Hap to the envelope disposed and large enough to form a complete lining to the envelope when carriedr on the skeleton member, and a layer of fibrous material on the outside of said envelope, the chemical material bein such as to react exothermically with a liquid and the fibrous material being capable of acting as a distributor of the liquid reagent to said chemical material.

ln testimony whereof I aiiix my si nature.

PETER SART RY.
